Long Beach Municipal Urban Stormwater Treatment Facility

The Long Beach Municipal Urban Stormwater Treatment Project (LB-MUST) is a comprehensive and innovative regional project.

It will intercept and treat dry weather runoff, and first-flush storm flows generated within the City of Long Beach before discharging to the Los Angeles River and Estuary. The centralized downstream advanced treatment facility has a planned capacity capable of collecting and diverting approximately 41% of the City’s 12,200-acre watershed.

The LB-MUST is a prime example of a project in the Lower Los Angeles River Watershed that provides incentives for water agencies throughout each watershed to collaborate in managing the region’s water resources and setting regional priorities for water infrastructure and improving the region’s water self-reliance. This is a multi-benefit infrastructure project that achieves many essential goals such as:

— Advancing local hire and job training goals.

— Using nature-based solutions.

— Providing benefits to disadvantaged communities and economically distressed areas.

— Providing inspiration and education to other agencies and the community, such as delivering multi-benefit solutions to address community challenges.

Colin Averill, PE, Civil Engineer, City of Long Beach Public Works, Engineering Bureau: “Long Beach continues its commitment to improving water quality by delivering an innovative project to treat stormwater and urban runoff with capacity for a substantial portion of the City’s watershed. Sustainability extends beyond the project limits with water reuse, community, and environmental benefits that will support expanded greenspace along the LA River.”
